INK-DISTRIBUTER FOR PRINTING-PRESSES- Specification of Letters Patent.

Patented Jan. 9, 1906.

Application filed June 7, 1905- Serial No. 264,039.

Printing-Presses, of which the following is a specification.

My invention relates to a spreading-roll to work in conjunction with the inking-roll of a lithographic or printing machine; and it consists of certain improvements upon the construction and arrangement shown and described in my prior patent, No. 678,019, granted July 9, 1901, for an ink-distributer.

The features of the invention are more fully set forth in the description of the accompanying drawings, forming apart of this specification, in which Figure 1 is a sectional elevation of my improved roll in position for use. Fig. 2 is a central section of one end of the roll with my improved reciprocating mechanism. Fig. 3 is a section on line a: 00, Fig. 2. Fig. 4 is a top plan view of a portion of the bushing and sleeve in which the reciprocating mechanism is contained. Fig. 5 is a perspective view of the thread-engager. Fig. 6 is a section on line w w, Fig. 2. Fig. 7 is a top plan view of the roll-supporting mechanism.

I have shown in the drawings only so much of the printing-machine as will serve to illustrate the operation of the particular features to which this invention relates.

1 represents the frame of a machine. 2 represents the reciprocating platen thereon.

3 represents the inking-roll journaled in brackets 4 upon the frame of the machine, the said roll being one ofia series in the machine contacting the form and taking rotary movement therefrom in opposite directions as the form is reciprocated.

5 represents the ink distributing or spreading roll, which is shorter in length than the inking-roll, the upper periphery of which it contacts. The mechanism forming the subjectmatter of this invention is designed to laterally reciprocate this spreading-roll from one end of the inking-roll to the other end as the inking-roll is respectively rotated in reverse directions. This ink-distributing roll consists of a sleeve or hollow cylinder, as shown in Figs. 2 and 8. Passing centrally through this sleeve 5 is a rod 6,having formed thereon at one end the Worm 7. The sleeve-roll 5 rotates upon this rod 6 as an axis and is also reciprocated thereon longitudinally. Preferably the sleeve 5 is secured to the bushing 8, whichbushing has a directbearing on the rod 6. In the end of the sleeve 5 corresponding with the worm end of the rod 6 is a collar 9, through which the worm end of the rod 6 asses. The collar 9 is provided with the poc et or radial cut-out portion 10, (see Figs. ,2, 3, and 4,) extending from the outer periphery of the collar into the bore. Into this pocket, which is preferably round, is placed a worm-thread engager 11, (see Fig. 5,) which preferably has the yoke 12 on its lower end engaging into the thread of the worm, the upper face of this worm-thread engager being rounded ofi to form abearing upon the inner periphery of the sleeve 5. The upper face of this thread-engager has a recess 13 formed therein, in which is seated the coil-spring 14. This thread-engager has a loose fit in the pocket 10 of the collar 9, as indicated in Fig. 2, the upper end of the spring 14 engaging against the inner eriphery of the sleeve 5, so that this thread engager may have a slight amount of radial. movement in the said pocket, so as to have an easy driving engagement with the thread of the worm and to allow the thread-engager to have a slight swiveling action, which takes place when it engages the opposite ends of the worm. The collar 9 is secured to the bushing 8 by means of the screws or fastening devices 15, which are passed axially through the collar and into the bushing, as shown in Figs. 3 and 4. The rod 6 is held against rotation by the supports 16. (See Fig. 1.) The construction of the worm 7 and its cooperation with the thread-engager 11 are substantially the same as shown, described, and claimed in my said prior patent that is, when the thread-engager reaches the end of the Worm before the platen has reversed its direction of travel the ink-distributing roll will continue to rotate in the same direction, the Worm-thread engager riding idly around the end circular thread 30 without imparting longitudinal travel to said roll. When said roll is reversed, a cam 31 on the worm throws the thread-engager again into the spiral worm-thread for the reverse longitudinal travel of said roll. In the present invention the worm is a stationary element, while the worm-thread engager is a movable element. In order to constitute this roll a universal attachment, I preferably em loy the supporting mechanism shown in Fig. l, in which 17 represents brackets projected from opposite sides of the frame. 18 represents upright rods supported in said brackets and extending above the platen. 19 represents a sleeve secured on the upper end of each upright and provided with cars 20. This sleeve is composed of two hinged sections pivoted together and frictionally clamped upon the rods 18 by means of the nut 21. This sleeve is provided with a boss 22, into which is secured a horizontal rod 23. 24 represents a split sleeve adapted to be clamped upon rod 16 and like wise provided with a boss, into which the pposite end of rod 23 is secured. It is to be understood that this supporting arrangement is the same upon each side of the bed. This affords provision for vertical and horizontal adjustment, permitting this roll to be conveniently attached to the frame of the various kinds of lithographing and printing machines.

' In operation as the roll is rotated in one direction the thread-engager 12, secured to said roll, follows the thread of the Worm and feeds the roll 5 longitudinally on rod 6 in a corresponding direction, and when the roll 5 is reversed in rotation a reverse longitudinal feed is imparted to the roll 5.

Havmg described my invention, I cla1m- 1. In a machlne of the class described, a bed, an 1nk-d1str1but1ng sleeve-roll, a main inking-roll contacting the same, a wormrod passing through the sleeve, a thread-engager carried by the sleeve, means for holding said rod stationary, consisting of an upright rod secured at its lower end to the bed and projecting above the same, a horizontal rod extended toward the bed, a vertically-dep ending rod to the lower end of which the wormrod is' secured, and adjustable connections between said rods adapted to make adj ust ments in various planes, substantially as described.

2. In a machine of the class described, an inking-roll, a contacting ink-distributing sleeve-roll, a rod having a single Wormthread at one end with devices at each end of the thread for reversing the thread-engager, means for holding said rod rigidly within said sleeve, a threadengager swiveled in the end of the sleeve and having spring-controlled engagement with the worm, and a bearingbushing secured to the sleeve within the same engaging the rod and adapted to rotate thereon while being reciprocated on the rod by the Worm-driving mechanism, substantially as described.

In testimony whereof I have hereunto set my hand.
